You can edit a curve using control points and edits of another curve type. For example, you don't have to create a B-spline curve to use the B-spline control points. If a curve or surface curve can be represented in B-spline form, you can edit it as a B-spline curve.
To edit a curve as another curve type:
- Select a curve.
- Click Curve Tools tab > Curve Type panel and select Bézier,
G2 or B-spline.
Note: Only options that are applicable to the selected curve are available.
Note: If you choose to edit a G2 or B-spline curve using the Bézier handles, the G2 or B-spline continuity of the curve may not be preserved.
Tip: Only limited options are available on the Manage tab when editing a curve as a B-spline curve.
